Fan noise

Are there any problems with the fan noise? IS it loud or can you hear it at all? I currently have the Lenovo Yoga 920 and the fan is so loud!!! I need one with no fan noise or very very very quite noise.

Fan running loud on brand new desktop computer

The first day was fine. Second day, fan is loud and seems to be running at full speed. Didn't load anything yet. So far I like Windows 10 after having Windows 7, but I hate the fan noise. Any and all suggestions greatly appreciated.

Thanks!!!
